According to Cecchi's book "In 1985 the family grew by a further 12 lenses. They mostly involved new and interesting optical constructions, characterized by special glasses, high speed and better facilities". He doesn't say anything about the glass in the A20/2.8. Nor does one of my old brochures. However, the brochure does say it has a "Pentax original Floating Mechanism". So I guess you'll be ok if it falls into a bucket of water. -- Cheers, Bob
